Summary Verdict
The 2019 Chevrolet Silverado 2500 HD demonstrates strong overall reliability, especially concerning its core powertrain components. The 6.0L V8 and the robust Allison transmission are generally trouble-free. The 6.6L Duramax Diesel, while powerful, has a few documented issues, primarily related to the Diesel Exhaust Fluid (DEF) system and glow plugs, which can lead to starting problems or warning lights. Electrical gremlins, such as infotainment system glitches and occasional battery drain, are also reported but are not considered widespread critical failures. Exterior and interior components are largely free of significant reliability concerns. For owners of the Duramax diesel, proactive maintenance and awareness of DEF system requirements are advisable.
